Can I ask where you got your hot bed plate from? See if their web site says anything intersting.by Dust - New Zealand RepRap User Group
You really need to check the wiring of the HBP and verify the resistance with a multimeter if its 5.5 ohms you need to lower it. I have 30A 12 volt supply, but since you dont. I wouldnt put them all in parallel either. So you should try a combination. Join the red to the input of two resitors, connect the other ends two each other and the input of the other two resitors and then end of thaby Dust - New Zealand RepRap User Group
Yes I would try running them all in parrallel Also check what amperage you power supply can put out on the 12v rails (should be written on it) Should be at least 16amp.by Dust - New Zealand RepRap User Group
These are simply power resistors, being used as heaters, quite common on repraps. details on the part Depensing on how this is wired, combination of parallel and serial will determine the final resistance and have a bareing on how hot it can get. If you description is correct you have a resitance of 5.5 ohms, wich sounds really high (my PCB HBP is about 1ohm) Running them all in parallel thby Dust - New Zealand RepRap User Group
Many are starting to run their steppers on 24volt. Gives alot more power and a higher top speed. And yes they are good for 24volt Heated bed pates Here is a nice doc on going 24v with ramps if anyones interstedby Dust - New Zealand RepRap User Group

Caps are also 16v, so if your thinking of running a 24 volt system, you will have to upgrade them. The smaller caps do look like they have been replaced with surface mount. To what effect if any.. who knows.by Dust - New Zealand RepRap User Group
I think you chasing red hearings, no one has reported any date based bugs. The controller also doesn't do anything date related. From what I can see the first image is just weird... no idea where W is coming from.

Some people have started to run into speed limitations of the standard atmega electronics just being to slow. As for is it will improve your speed? This depends on your physical machine constraints. Electronics cant overcome friction issues or thermal conductivity issues (slow hot end) For now It will allow faster uploads to SD if you use that (full USB speed) It also shouldnt have any slby Dust - New Zealand RepRap User Group

You want a 4pi then [0xfb.com] Sprinter firmware has been ported to it. The main author of Sprinter (Kliment) Designed the 4pi You of course cant have the exact same firmware as they are completely different CPU's Also the 4pi for example has digital stepper driver pots (ie controlled via gcode) and more of everything, so the firmware needs to be updated for that.by Dust - New Zealand RepRap User Group
I have seen one set that someone CNC'ed His comments where "so loud, don't bother" But they did look really nice. Cost was unknown, since he had access to a CNC machine as part of his job, he just did them himself. But its really not needed. Printed extruder gears works really well. Injection molded may be fractionally stronger, but they will also be a lot heavier.by Dust - New Zealand RepRap User Group
That a very simple device. It doesn't provide the standard enable, step and direction interface so will not work with normal firmware (with out additional hardware) and it only does half stepping so It will be noisy and jerky. reprap used to use them before everyone moved to pololu seeby Dust - New Zealand RepRap User Group
